IPC: H01Q1/24
Filed: 1991-07-13
Abstract: An antenna assembly comprises an elongate antenna element 11 mounted in a support 5 and movable between a retracted position (see Figure 2) and an extended position. A helical antenna element 12 is carried at one end of the elongate element. The support 5 comprises a pair of concentric conductors 9, 10 which provide a coaxial feed to the antenna elements 11, 12. Suitably the support 5 comprises a dielectric tube 6 having respective conductive portions 9, 10 provided on the inner and outer faces thereof. The elongate antenna element is slidably mounted within the central conductor 9.
